How to enable effective top-hole cementing in high-pressure shallow water and gas

Achieving successful isolation of unconsolidated sands can be challenging. The Caspian region is notorious for its unconsolidated formations and has previously imposed a lot of costs for major operators in that region.

Effective top-hole cementing with MPC®

A few years back, the major operator BP had previously imposed a lot of costs in the Caspian Sea due to the high-pressure shallow water and unconsolidated sands. To enable effective top-hole cementing, Managed Pressure Cementing (MPC®) was vital to this operation.

Significant cost and time savings

The MPC® system used in the Caspian Sea meant the operation was done much more safely as well as it resulted in significant cost and time savings for BP due to mitigation of pressure-regime related issues.
